Martijn Dekker 52067c3d37 Backport atomic job locking from ksh 93v- beta ... Something similar was previously done in 07cc71b8 from a Debian patch, and eventually reverted; it redefined the ast atomic functions asoincint() and asodecint() to be gcc-specific. This imports the upstream version from the ksh 93v- beta instead. This commit is based on an OpenSUSE patch: https://build.opensuse.org/package/view_file/shells/ksh/ksh93-joblock.dif src/cmd/ksh93/include/jobs.h: - Replace job locking mechanism with the 93v- version which uses the atomic libast functions asoincint(), asogetint() and asodecint(). See: src/lib/libast/man/aso.3 src/cmd/ksh93/sh/jobs.c: job_subsave(): - Revert gcc optimiser bug workaround from c258a04f. It should now be unnecessary.		2021-02-02 17:38:19 +00:00
